Laboratory for Space Systems (LSS), Tokyo Institute of Technology (Tokyo Tech), succeeded in launching a Tokyo Tech CubeSat, CUTE-I (CUbical Tokyo Tech Engineering satellite-I) on June 30, 2003 by a Eurockot's rocket, ROCKOT from Plesetsk cosmodrome in Russian Federation. CUTE-I is one of the first launched CubeSats and is now orbiting a sun-synchronous orbit at an altitude of 820 km, inclination of 98.7deg, together with other 4 CubeSats launched at the same time. As there is no preceding research on picosatellite's temperature and attitude history for more than one year, observation and analysis of data measured with several sensors of CUTE-I is invaluable. In the paper, the latest results of On-Orbit flight data analyses are reported.
